Here's some simple script that will highlight ALL
options and with a few modifications, you can make it
so it selects only the ones you wish, either by hard-coding it,
or by creating an array of values, splitting it and checking if the
current option is in the list of options to be selected, while looping
through your options collection on the dropdown element.
==============================
<form name="test">
<select name="mySelect" multiple size="4">
<option value="1">1
<option value="2">2
<option value="3">3
<option value="4">4
</select>
<input type="button" onclick="selectMultiple()" value="Select 'Em">
</form>
<Script language='Javascript'>
<!--
function selectMultiple(){
var objForm = document.forms['test']
var objEl = objForm.elements['mySelect']
for(var x = 0; x < objEl.options.length; x++){
objEl.options[x].selected = true
}
alert(objEl.options.length)
}
// -->
</script>
==============================
Hope that helps,
